KT88-TK Vacuum Tube, Matched Pair

The KT88-TK Vacuum Tube, Matched Pair is a premium set of two big-bottle power tubes selected for balanced operation in compatible amplifiers. Manufactured in partnership with JJ Electronic in Slovakia, the pair delivers strong output, an expanded low end, and a rich, harmonically dense tonal character.

Each tube undergoes rigorous testing, cryogenic treatment, and an extensive burn-in process for consistent and dependable performance. The matched pair is suited to KT88 amplifier upgrades and many amplifiers using 6550 tubes, though compatibility and bias requirements should be confirmed with the equipment manufacturer or a qualified technician.
